Terminated login methods
Here you will find information about login methods that will terminate: Altinn code letter, SMS code, password and business certificate at altinn.no.
From November 23, 2023, the button "Proceed to more login methods" will be replaced with the button "Log in without a birth number/D-number."
Logging in with Altinn code letter, SMS-code, or password alone, as well as enterprise certificate, will eventually be phased out. We recommend using MinID or another login method via ID-porten.
If you do not have the option to do this, you can still find login options with Altinn code letter, SMS-code, or password and Enterprise certificate for the time being here: https://www.altinn.no/ui/Authentication
This login change only applies to altinn.no and does not affect machine-to-machine communication (accounting and payroll systems). It will still be possible to authenticate with a enterprise certificate in those systems. It will also be possible to log in to accounting and payroll systems with Altinn code letters and SMS codes until they are phased out gradually.
To use this log-in method, you have to order a code letter from Altinn. Once a new code letter is used, any older code letters are invalid.
An Altinn code letter has 30 codes, and can not be used for logging in using MinID (that has its own 20 code letter).
To use this log-in method you first need to log in using another method, and register a password and mobile phone number under Profile → Advanced settings → Login information.
This method is commonly used by users logging in using a computer system with Altinn integration.
To use this log-in method you need to register a password under Profile → Advanced settings → Log-in information. This log-in method only gives access to a few of the Altinn services.
